SETTINGS PRODUCT SETUP COMMUNICATIONS EGD PROTOCOL SLOW PROD EXCH 1(2) CONFIGURATION
Slow EGD exchanges (500 to 1000 ms) are generally used for the transfer and display of data items. The settings for the
fast and slow exchanges are as follows.
EXCH 1 DESTINATION — This setting specifies the destination IP address of the produced EGD exchange. This is usually
unicast or broadcast.
EXCH 1 DATA RATE — This setting specifies the rate at which this EGD exchange is transmitted. If the setting is 50 ms, the
exchange data is updated and sent once every 50 ms. If the setting is 1000 ms, the exchange data is updated and sent
once per second. EGD exchange 1 has a setting range of 50 to 1000 ms. Exchanges 2 and 3 have a setting range of 500 to
1000 ms.
EXCH 1 DATA ITEM 1 to 20/50 — These settings specify the data items that are part of this EGD exchange. Almost any data
from the T35 memory map can be configured to be included in an EGD exchange. The settings are the starting Modbus
register address for the data item in decimal format. See the Modbus memory map in the UR Series Communications
Guide for details. The Modbus memory map display shows addresses in hexadecimal format. Convert these hex values to
decimal format before entering them as values for these setpoints.
To select a data item to be part of an exchange, it is only necessary to choose the starting Modbus address of the item.
That is, for items occupying more than one Modbus register (for example, 32 bit integers and floating point values), only the
first Modbus address is required. The EGD exchange configured with these settings contains the data items up to the first
setting that contains a Modbus address with no data, or 0. That is, if the first three settings contain valid Modbus addresses
and the fourth is 0, the produced EGD exchange contains three data items.
